Does Preoperative Coffee Consumption Prevent Intraoperative Hypotension in Cesarean Section Surgeries?

Objective: In this study, we evaluated the effects of a cup of coffee given to patients before surgery in a cesarean section by means of intraoperative hypotension, ephedrine requirement, and the incidence of post-dural puncture headache (PDPH).

Methods: A total of 140 patients undergoing elective cesarean section with spinal anesthesia were included in this study. Participants who drank a single cup of filtered coffee two hours before spinal anesthesia were included in the coffee group, and those who drank water were in the control group.

The use of regression tree method for Sentinel-2 satellite data to mapping percent tree cover in different forest types.

Quantifying forest systems is of importance for ecological services and economic benefits in ecosystem models. This study aims to map the percent tree cover (PTC) of various forest stands in the Buyuk Menderes Basin, located in the western part of Turkey with different characteristics in the Mediterranean and Terrestrial transition regions Sentinel-2 data with 10-m spatial resolution. In recent years, some researches have been carried out in different fields to show the capabilities and potential of Sentinel-2 satellite sensors.
